Phosphorus in Pig Nutrition
In order to reduce P excreted by pigs, P dietary supply should be better adjusted to the requirements and strategies to improve P availability should be implemented. The use of a feeding system relying on P apparent digestibility is recommended. This allows the reduction of safety margins when formulating pig diets, resulting in a decrease in P excretion. Low digestibility of P in feed ingredie...
متن کاملPhosphorus Nutrition of Ruminants
Most Australian soils are derived from parent material which is low in phosphorus. Soils of low phosphorus status support early maturing, grass dominant pastures with a short summer growth period and hence lengthy period of senescence. Phosphorus in these grasses may be as low as 0.02 g P/100 g OM during senescence (Robinson and Sageman 1967) and may only reach 0.15 g.P/lOO g OM during active g...
متن کاملFurther Aspects of Sulphur Nutrition of Legumes
THE KEY to improving the native tussock grasslands of the South Island is to obtain good legume growth. In these areas, the main nutrient deficiencies which limit the growth of legumes are sulphur, phosphorus and molybdenum. Sulphur deficiencies are very widespread (Walker et al., 195.5; Lobb and Bennetts, 1958; McLeod, 1961). The manner in which a rational fertilizer programme was formulated f...
متن کاملPhosphorus and Nutrition in Chronic Kidney Disease
Patients with renal impairment progressively lose the ability to excrete phosphorus. Decreased glomerular filtration of phosphorus is initially compensated by decreased tubular reabsorption, regulated by PTH and FGF23, maintaining normal serum phosphorus concentrations. There is a close relationship between protein and phosphorus intake. In chronic renal disease, a low dietary protein content s...
متن کاملEffects of Forage Management on Pasture Productivity and Phosphorus Content
The objectives of the current study were to determine the amounts of aboveand below-ground plant biomass production, P uptake by forage, and P concentration of cool-season grass forage as influenced by management and season. Five forage management treatments were evaluated over 3 years in smooth bromegrass (Bromus inermis Leyss) pastures. Management practices were: ungrazed (U), hay harvest/fal...
